Abstract
The present disclosure comprises a ventilation system in a flexible heat exchanger system of a seating assembly. It relates to a flexible layer having perforations positioned underneath the surface of the seat that enables ventilation to control temperature and humidity. The seating assembly comprises of a plurality of layers wherein the seating assembly has an upper layer upon which the occupant is in direct contact with, a middle layer having a heat exchanger system with perforated cooling pads or ventilation system for ventilation and a lower layer which is a cushioned layer having vents. The ventilation system includes but not limited to an array of holes, pores and cavities for maintaining temperature and humidity thus making the seating assembly breathable.
Claims5
A seating assembly comprising:
- a seat portion including:
- an upper layer forming a seating surface;
- a middle layer including a flexible heat-exchanger system, the flexible heat-exchanger system comprising a single flexible sheet having:
- a top layer and a bottom layer joined to one another by heat-sealing to define a plurality of heat-exchange medium channels arranged in a plurality of rows extending across a width of the single flexible sheet and a plurality of columns extending across a length of the single flexible sheet;
- the plurality of heat-exchange medium channels in all of the plurality of rows being in fluid communication with one another and the plurality of heat-exchange medium channels in all of the plurality of columns being in fluid communication with one another, and all of the plurality of rows being in fluid communication with all of the plurality of columns;
- each of the plurality of rows intersecting each of the plurality of columns to define a plurality of enclosed areas of the single flexible sheet;
- and
- a plurality of ventilation blocks, each ventilation block being located within a respective one of the plurality of enclosed areas, each ventilation block comprising a sheet portion of the single flexible sheet and at least one ventilation hole extending through the flexible sheet;
- and
- a lower layer beneath the flexible heat-exchanger system, the lower layer comprising a cushioning layer having a plurality of vents;
- and
- a seat back portion extending upwardly from the seat portion;
- a plurality of heat-exchange medium connection tubes connected to the plurality of heat-exchange medium channels;
- and
- a secondary heat-exchange system connected to the plurality of heat-exchange medium connection tubes.
